Abstract
Given their desirable shielding properties, 5 polymer composite shields reinforced with tungsten were selected
and their effects as gamma shields on fetal dose reduction were investigated. According to the results, the
selected shields reduce the fetus brain, the fetus lungs, the fetus kidneys, and the total fetus dose almost 34.17%-
41.19%, 20.47%-25.08%, 9.27%-12.13%, and 15.39%-18.69%, respectively, at tube voltage of 80 kVp. At the
higher tube potentials, the values of dose reduction were smaller. Moreover, it was observed that polymers
named PHEMA-WO3 and RS-U-30 had an excellent shielding ability among the other studied composites.
